I have a Linux box connected to a simple DSL router (along with other
machines on the home network). This box is intended as an off-site
storage server for my office. Taking advantage of some rsync scripts,
I have a very simple yet complete off-site backup solution. My
question is in bandwidth management.
I want to use this box for other purposes. It has a single NIC,
connected to the switch/router. Operating within my home LAN, I
should be able to communicate with it at the typical full-duplex
100BaseT speeds. However, when it's involved in the archive process,
the DSL connection (5M/512k) get saturated. I wanted to setup some
sort of shaping on this box to control how much of the DSL connection
it consumes.
I initially went to wondershaper/ctshaper - but I realized that this
is actually going to hurt me. With ctshaper enabled, with the DSL
tuned settings of 5M/512k - I've absolutely crippled its ability to
communicate with the LAN.
How can I achieve the clean communication with the DSL, reserving some
available bandwidth for other purposes - yet leave communication with
the local network at full? Do I need to define multiple virtual
interfaces?
It just hit me that this is probably incorrect in my particular case -
since I'm using OpenVPN for the conenction I can apply the throttling to
the tap interface. But - my question still remains how I would go about
doing this type of control if I were actually using just the one interface.
